IMPROVEM ENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 29,707, dated August21, 1860.

To all whom it may concern:

Be it known that I, T. W. MoDILL, of Oquawka, inthe county of Hendersonand State of Illinois, have invented a new and Improved Cultivator; andI do hereby declare that the following isafull, clear, and exactdescription of the same, reference being had to the annexed drawings,making a part of this specification, in which- Figure l is a sidesectional vicwof my invention,taken in the line as m, Fig. 2; Fig. 2, aplan or top view of the same.

Similar letters of reference indicate corre sponding parts in thetwofigures.

The object of this invention is to obtain a cultivator which may bereadily manipulated, or which may be attended and guided with but littlelabor. This result is obtained in consequence of provision being madefor controlling the implement with facility by giving some of its plowsan independent adjusting-movement independently of the draft-movement,whereby the implement may be kept in its proper course and obstructionsreadily passed over, the implement, also, by a very simple adjustment,admitting of being readily drawn from place to place.

The invention consists in a novel arrangement of adjustable shares,substantially as hereinafter described, whereby the desired end isattained.

To enable those skilled in the art to fully understand and construct myinvention, I will proceed to describe it.

A represents an axle, and B B wheels attached to the arms thereof. Thecentral part of this axle is curved in bow form, as shown at a, in orderthat it may form no obstruction to the plants as the machine is drawnalong.

To each end of the axle A there is attached a bar, I). These bars areparallel with each other, and are connected at their back ends by across-piece, c, which is also curved at its center in bow form, as shownat d, the bow 01 being in line with the bow at of the axle, the formerbeing for the same purpose as thelatter. The front ends of the bars bhave each a gooseneck, 0, attached to them by bolts j, which passthrough oblong eyes 9 on the bars, and allow the goose-necks a certaindegree of longitudinal play. The goose-necks e e are attached to a bar,h, which has the draft-pole B connected to it.

Through the axle A,at equal distances from each side of its center,there pass bolts it, both of which are shown in Fig. 2. The back ends ofthese bolts are provided with beads, and the bolts pass through clevisesj j, attached to the front ends of bars k It. (See more particularlyFig. 1.) This mode of attaching the bars 70 k to the axloAadmits of theformer having a lateraland turning-movement. Each bar I) has a handle,Z, attached to it, and also an upright, m, the latter being connected bytraverse-bars n n, which are perforated at their ends and secured bypins 0, which pass through the uprights m. The back ends of the bars 70it have each a pintle, 19, attached, and said pintles pass through loopsor guides q g, which are attached to the cross-piece c, said guidesbeing sufficientlylong to allow the bars k k a certain degree of lateralplay or movement.

To each bar I) a plow-standard or foot, 'r, is attached bya bolt, 8, andthe standards or feet are braced by rods t, which have jum-nuts u u onthem-two on each-between which the standards or feet are placed. To thelower end of each foot or standard a plow, o, is attached. To each barkthere is also attached a similar standard or foot, 20, the lower endsof which ha 'e plows a secured to them. The standards or feet 20 arebraced by rods b, having jamnuts 0 on them.

From the above description it will'be seen that as the implement isdrawn along the bars 76? 7c and plows a may be moved laterally, eitherto the right or left, and in case of the team moving either to the rightor left, out of a proper course, the plows a may be kept in a directline until the team is brought back to the proper place. In case, also,of the plows striking obstructions which may be in their path, they willbe readily deflected or turned so as to pass over or by the obstruction.This arrangement of the bars 70 7c renders the ma nipulation of theimplement very easy, greatly reducing the labor attending the use of thecultivator.

When necessary-as, for instance, in furrowing--the bars 70 k may bedetached and the plows u only used. The depth of the plows o,

I do claim as new and desire to secure by Letters Patent V Thearrangement of the axle A and bars I) b 70 7c and cross-piece 0 with theloose connection of the draft-pole B to the machine, substantially asand for the purposes set forth.
